Your comprehensive race day forecasting
We've come a long way from 40 degrees and cool, rainy headwinds at the start, like last year, to the mid 60s, occasional rain and tail/cross winds, which is where we are now. A warm front will move through sometime Sunday evening, and the question is when because the faster it moves through, the faster the rain will enter the forecast area and move out with a potential for a break in the action during the race. Since we're getting down to specifics now, here's what we know:
1. It's going to be warm and humid, and likely in the mid 60s. For light, faster runners, this means about a 4% decrease in performance from optimal temperatures of 40 degrees. For heavier. slower runners, this could mean up to a 25% decrease in performance. This could increase your time from 30 to 60 minutes if you're in the slower waves, so let your families know! Take it easy out there, take in fluids when your'e thirsty, and listen to your body. 2. There will be a tailwind all the way to Boston. This won't help too much because you'll be in a crowd, but it won't hurt you. You'll feel it most while in the hills as you crest each one and land above the crowd. We aren't looking at 2011 tailwinds of 25 MPH, but probably closer to 15 MPH. 3. It will rain, but it won't be for the entire race. Expect breaks, and the potential for sunshine. If there's lightning, expect it before the race, and maybe in the later afternoon. While it's too late to heat train, hopefully you've been paying attention to my prior forecasts explaining that it's always a good idea, and you'll be prepared. Otherwise, find a sauna or start overdressing NOW so you're at least partially acclimated! WAVES 1/2: Hopkinton: 64, tailwinds of 15 MPH, scattered showers. Newton: 67 to 70, dry, warm/humid, with SW to S winds at 12 MPH. Boston: 63, S/cross winds with some tailwinds, 14 MPH, dry. WAVES 3/4: Hopkinton: 65, tailwinds of 15 MPH, showers ending/dry. Newton: 67 to 70, dry, warm/humid, with SW to S winds at 12 MPH. Boston: 69, tailwinds, 14 MPH, raining. Look for updates Sunday night and Monday morning!

Boston is one of the best city's in the entire world right now. I mean, the fact that they own a great amount of championships in the world of sporting right now. I feel like their NBA team is not getting the amount of appreciation that they deserve. I mean, they have a young core of players who are approaching their primes. I feel like in a couple of years, Boston can be an basketball dynasty I really feel like it.
